Rare earths hopeful Critica has appointed mining executive Jacob Deysel as CEO, with a mandate to advance the company’s flagship Jupiter project in Western Australia and spearhead a strategic review of its Tasmanian tin and tungsten assets.

Deysel, an executive with experience spanning Australia, Europe and the Americas, brings a track record in securing offtake agreements, early-stage partnerships and government support. 

“I have undertaken extensive due diligence on Critica’s assets and believe Jupiter has the potential to become a globally significant rare earth project,” said Deysel. “With its scale, grade, and location in Western Australia, we have a clear pathway for expeditious development through scoping and feasibility."

"I’m energised by the vision and potential of Critica to become a key developer in the critical minerals sector, underpinned by a strong ESG focus."

The Jupiter project, part of the broader Brothers project, is located between the Port of Geraldton and Mt Magnet. The company describes Jupiter as ideally placed to develop into a long-life rare earths mine aligned with Western supply chains.

Critica states that Deysel's experience, particularly his role at Uranium Energy and as founder of REE-focused Sheerartar Minerals, will be valuable for the company’s next phase. 

Critica already has a strong technical team in the rare earth sector, including Dr Stuart Owen (geologist), Dr Natalee Bonnici (geologist / geometallurgist) and Dr Hien Dinh (mineral processing / metallurgist).

"Critica’s first-pass beneficiation testwork has already achieved an 830% grade uplift at >50% REE recovery. Jacob’s hands-on experience with REE feedstocks and beneficiation processes delivers the strong potential for rapid advancement and commercialisation of these outcomes."

Deysel will also oversee a strategic review of Critica’s Mt Lindsay project in Tasmania, which the company describes as one of the world’s largest undeveloped tin and tungsten assets. These metals are increasingly sought after as global supply chains tighten and demand for critical minerals grows.

Owen will step down as interim CEO, effective immediately, as Deysel assumes leadership of the ASX-listed junior.

Meanwhile, nonexecutive directors Tim Lindley and Nick Cernotta have opted to receive equity in lieu of cash fees from July 1, in accordance with Critica’s remuneration plan and subject to shareholder approval.
